Rhubarb Custard Pie

Rhubarb, technically a vegetable, is known for its very tart flavor and the fact that only the stalks are edible. There are many varieties of rhubarb, which accounts for how the stalks vary in color from a deep red to a pale green. Although all kinds have a delicious flavor, this pie looks prettiest with the red-stalked varieties. Look for thinner stalks, as they will be more tender and less fibrous than thicker stalks.
